Polyelectrolyte assisted charge titration spectrometry: applications to latex and oxide nanoparticles
F. Mousseau, L. Vitorazi, L. Herrmann +2
The electrostatic charge density of particles is of paramount importance for the control of the dispersion stability. Conventional methods use potentiometric, conductometric or tur…
Isothermal titration calorimetry as a powerful tool to quantify and better understand agglomeration mechanisms during interaction processes between TiO2 nanoparticles and humic acids
Frédéric Loosli, Letícia Vitorazi, Jean-François Berret +1
The association processes between engineered TiO2 nanoparticles and Suwannee River humic acids are investigated by isothermal titration calorimetry and by measuring the exchanged h…
Towards a better understanding on agglomeration mechanisms and thermodynamic properties of TiO2 nanoparticles interacting with natural organic matter
Frédéric Loosli, Letícia Vitorazi, Jean-François Berret +1
Interaction between engineered nanoparticles and natural organic matter is investigated by measuring the exchanged heat during binding process with isothermal titration calorimetry…
Preventing corona effects: multi-phosphonic acid poly(ethylene glycol) copolymers for stable stealth iron oxide nanoparticles
V. Torrisi, A. Graillot, L. Vitorazi +4
When disperse in biological fluids, engineered nanoparticles are selectively coated with proteins, resulting in the formation of a protein corona. It is suggested that the protein…
Self-assembly of complex salts of cationic surfactants and anionic-neutral block copolymers. Dispersions with liquid-crystalline internal structure
Leticia Vitorazi, Jean-Francois Berret, Watson Loh
We report the synthesis of complex salts made from the cationic surfactant dodecyltrimethyl-ammonium and diblock copolymers poly(acrylic acid)-block-poly(acrylamide) of different m…
